  • Patent number: 4404982
    Abstract: A rupturable pressure relief apparatus which is non-fragmenting and which is particularly suitable for liquid and low pressure gas service. The apparatus includes an annular rupture disk having an annular flange portion connected to a concave-convex portion by a circular transition connection. The concave-convex portion includes a groove in a side thereof creating a substantially circular line of weakness therein and at least one concave-convex hinge reinforcing member is attached to a side of the concave-convex portion of the rupture disk. The hinge reinforcing member is positioned and is of a shape whereby upon rupture of the rupture disk, the concave-convex portion tears along the line of weakness created by the groove and bends about an integral untorn portion corresponding with the hinge reinforcing member.
